  • Abstract
    A circularly polarized, planar cross dipole antenna is presented with an electrical size, kr, of 0.65. Miniaturization of the antenna is achieved by employing top-loading on both ends of the crossed dipoles. Short stubs are implemented to boost the reduced radiation resistance. The antenna is printed on Rogers RT/Duroid 5880, having a dielectric constant, εr, of 2.2, and a thickness of 3.2 mm. The antenna operates at 912 MHz, where the maximum realized gain of the antenna is 1.37 dBic and the axial ratio is below 3 dB.
